Three-loop renormalization constants and anomalous dimensions are derived analytically for three-quark operators with derivatives in QCD, confirming prior N=0 results and enabling lattice matching.
First NLO QCD calculation of fully charm tetraquark production using TMD factorization and NLL resummation, with LDME fitted to LHCb/CMS data on X(6900) and predictions for distributions.
Algorithms that factor denominators in IBP coefficients inside the FUEL interface reduce reconstruction cost and improve robustness of large-scale Feynman integral reductions.
